Question

how to find vertical asymptote of f(x)=1/x^2 and on calculator?

Answer 1

verticle retricemotote is at x=0 because that's where function is indeterminant

Answer 2

is it because it says ERROR on the calculator?

Answer 3

yes

Answer 4

you can't divide by 0

Answer 5

oh so for x^2-2/x^2-x-2 would equal to vertical asymptote of -1 and 2 right?

Answer 6

right!
x^2 - x -2 factors into

(x -2 )(x+1)=0

so vertical retricemtote is at x=-1, 2

Answer 7

it should read "asymtote"
